The Achilles heel for many advanced treatment processes for biosolids being considered is biosolids handling. This webinar will review some of those challenges and how they have been overcome using combinations of mechanical optimization, instrumentation, and operational adjustments.

Presentation 1: Solids Measurements and Control in Dewatering Processes
Will discuss the use of solids measurements in optimizing wastewater processes. In particular, how solids measurements contribute to improved dewatering by reducing polymer, hauling costs, and improving dewatering processes.
Antonio Guerra, Regional Manager, Canada/USA and Country of Mexico, Valmet

Presentation 2: Biosolids Cake Pumping Life Cycle Analysis - A True Operators Story
After decades of continuous operation at municipalities across North America, hydraulic piston pumping has proven itself a reliable method for transporting dewatered biosolids cake. Due to the heavy-duty nature and higher capital costs associated with conveying biosolids cake, piston pumps have been applied to transporting higher cake solids over longer pumping runs. Piston pump systems afford operational resilience when compared to other conveyance options.

Presentation 3: Reducing Dewatering Costs Through an Optimization Program
The Eastern Municipal Water District (District) in Perris, California, operates four regional water reclamation facilities (RWRF). Dewatering (centrifuges and standby belt filter presses) and subsequent transport/land application (hauling) of biosolids represented an annual District-wide operating cost of $3.7M from 2011-2014. In late 2014, the District embarked on a concentrated effort to reduce dewatering costs across its facilities by 5 to 10-percent, resulting in annual savings of $185,000 to $370,000. This dewatering optimization program included initial performance evaluations, equipment/field optimization training, and implementation of recommended system improvements. Major recommendations made by the project team and the subsequent performance metrics at two of the facilities will be presented.
